Statistical matching is a method of data integration for data sources that do not share the same units. It could produce rapidly lots of new information at low cost and decrease the response burden affecting the quality of data. This paper proposes a statistical matching technique combining k-NN (k-nearest neighborhood) and regression methods. We select k records in a donor file that have similarity in value with a specific observation of the common variable in a recipient file and estimate an imputation value for the recipient file, using regression modeling in the donor file. An empirical comparison study is conducted to show the properties of the proposed method.

E-commerce is now a familiar form of commercial transaction, especially in the transactions between businesses. This online transaction poses a good deal of problems to the traditional tax system and administration. Realignment of tax system and tax administration in the e-commerce is one of the major topics on the International problem. In the area of consumption tax, they reaffirmed the destination principle. They agreed to decide the recipient's business presence and usual residence as the place of consumption. In the area of consumption tax, they reaffirmed the destination principle. They agreed to decide the recipient's business presence and usual residence as the place of consumption. Currently, the Korean VAT law does not have a basis for taxation on international transactions that are considered to be services. Considering the tax revenue loss and the inequality between domestic suppliers and foreign suppliers when international transactions are not taxed, the Korean Tax Authority needs to amend the current law.

Nuclear transplantation technique is known as the most potential and efficient method for producing a large number of genetically identical animals from a single embryo. The technical development of nuclear transplantation in mammals and its application to the production of cloned animals are described. For the efficient and successful production of cloned embryos by nuclear transplantation, the right selection and micromanipulation of recipient eggs or embryos as capacious recipient cytoplasm, the adequate and benefitlal preparation of multiple totipotent embryonic cells as donor nuclei, and also the fusion technique are very critical. Recent studies approaching to these critical points are introduced and discussed. Up to date, the overall efficiency of production of cloned embryos and offspring in livestock is estimated to be low. Further technical development of nuclear transplantation will enable large-scale production of cloned livestock and in near future the commercial cloning of animals will become a reality.

Enterococcus faecalis KBL703 has three plasmids(p703/9, p703/5 and p703/4). Within p703/5, the specific DNA region that would confer replication function(replication origin) was searched by transformation experiments. In order to use as the recipient of transformation, two plasmid-cured strainsd were made from this strain. Four recombinant DNA constructs, each containing fragment of p703/5 and CAT(chloramphenicol acetyl transferase) gene were also made. And they were used to transform the plasmid-cured strains. Only one DNA construct containing 3.6 kb SalI fragment was stably maintained as plasmid in these strains. Additional experiment using another Enterococcus faecalis strain(ATCC29212) as a recipient was successfully done and it was confirmed that this newly constructed recombinant plasmid plasimid contained the replication origin from p703/5 plamid.

The development of embryos reconstructed by nuclear transfer is dependent upon numerous factors including the type of recipient cell, method of enucleation, the type of donor cell, method of reconstruction, activation, the cell cycle stage of both the donor nucleus and the recipient cytoplasm and the method of culture of the reconstructed embryos. Many of these points which have been reviewed extensively elsewhere (Sun and Moor, 1995; Colman, 1999; Oback and Wells, 2002; Renard et al., 2002; Galli et al., 2003b), here we will concentrate on main area, the production of suitable cytoplast and nuclear donor, nuclear-cytoplasmic coordination, oocyte activation, culture of reconstructed embryos, and the effects that this may have on development.

This study examines the importance of group identity (kin, friends, co-workers) when gift recipient changes among American and Korean consumers. Female college students and academicians completed a self-administered questionnaire. Four hundred fifty-eight respondents evaluated the perceived importance of group identity when buying an apparel gift for kin, friends, and co-workers. The results suggest that the importance of group identity may influence the type of gift a recipient receives. The results show that when buying a gift for kin, friends, and co-workers that both young and older American consumers place greater importance on self rather than the opinion of other group. The older and younger Korean respondents rated the opinion of each group (kin, friends, and co-workers) to be more important than self. Recommendations for future research on the affect of culture on consumer purchases are suggested.

The purpose of this study was to identify caregiving situations and to examine resources for adjustment among family caregivers of the elderly with dementia. Thereby the study can provide the basic information for the development of education programs for family caregivers through in-depth interview. The main result of this study was as follows : 1) The major problems identified by family caregivers I caring for the elderly with dementia were related to care recipient's toileting and to care recipient's confusion and wandering. 2) The family caregiver expressed feelings of burden including chronic fatigue, depression, guilt and frustration. 3) The factors influencing the adjustment of family caregivers for demented elderly were quality of relationship, motivation for caregiving, circumstances of caregiving, social support and coping strategies.

Since the day the Internet became a common and reliable mechanism for communication and data transfer, security officers and enthusiasts rallied to enforce security standards on data transported over the globe. Whenever a user tries communicating with another recipient on the Internet, vital information is sent over different networks until the information is dropped, intercepted, or normally reaches the recipient. Critical information traversing networks is usually encrypted. In order to conceal the sender's identity, different implementations have proven successful - one of which is the invention of anonymous networks. This paper thoroughly investigates one of the most common and existing techniques used during data communication for avoiding traffic analysis as well as assuring data integrity - the onion router (TOR). The paper also scrupulously presents the benefits and drawbacks of TOR.

Russia has an interesting history as a donor, recipient and re-emerging donor in international development assistance (IDA). This article introduces the history, policy and challenges of Russian IDA, and provides suggestions for such challenges. The main barrier to Russian IDA is the absence of a central government agency and Russia can learn from other country's experience. Concerning lack of data on the provision of assistance to each sector of IDA and the large number of recipient countries, Russia can learn from Korea particularly in education sector. With respect to building a system ensuring the efficiency of the Russian IDA works, a tool for analysis of the effect of the Russian IDA programmes may be drawn in consultation with international institutions or successful programmes of other donor countries.

The purpose of the study is to investigate the preference by emoticon types according to the gender of sender, emotion types of message and intimacy with the recipient. Results show that women mostly prefer to use dynamic and imaged emoticon than men. However, the preference of using text messages increases when both men and women express uncomfortable emotion. Especially, when users send family messages, they tend to prefer for text message. And when users send close friends messages, the preference for dynamic and imaged emoticon is high. When users send distant friends messages, the similar tendency is shown regardless of emotion. These results can provide the information to use emoticon in the filed of education and take advantage in digital education and mobile education.
